Hi,

I'm looking at some old code, and am having a problem with IE having
changed how accesses an object:

pages = window.parent.frames.item(1).document.all("position");

This works under Win200 and 6.0.2800.1106.

But not under WinXp and 6.0.2900.2180.

Does anyone know what IE might be looking for?

Thanks,

What does item(1) refer to?
What is "position"?

Not even MS is sure what IE might be looking for about 90% of the time.

An individual frame. In FF window.parent.frame[1] works.

> What is "position"?

An ID (yeah, I know, bad idea to have more than one element with the same
ID, I'll fix that next).

Heh. But I need to find out what it wants this time...

IE only code, gotta love it.

It's not just a "bad idea" as it is invalid HTML code and when presented
with invalid HTML anything goes.

Start with validating the HTML to make sure it isn't a multiple ID issue
as IE may make a collection of same-ID'ed elements (I don't remember to
be honest). Then, start debugging with alerts and find out what is
causing the error.

Didja already try debugging to see what fails? Like an alert and
removing the ending object each time until it works?

alert(window.parent.frames) etc.

What error did you get, btw? No permission or ?? W2K and XP seem
to sometimes have different security models.

Also, personally, I'd name the frames so you don't have to do the
frames.item(1) thingie. Ooops, never mind, I forgot that you said it
was old code.

Luck! - Kev

Yeah, it was a security problem -- MS's silly "Mark of the Web" wasn't on
the main page.

The frames were already named. Which means I can use
window.parent.frames.frameName, I just checked and IE recognizes it (both
on my development machine and when working).
